TC44B 2.5mm / 4.4mm Balanced audio Adapter

2.5mm or 4.4mm? We want both!

The TC44B is designed with two balanced output ports and both the 2.5mm and 4.4mm is simply plug and play. The 4.4mm output port is grounded connected, so it's more suitable to use with the balanced active speaker.

Double-sided symmetrical triangle

The TC44B looks like a triangle cheese that wrapped with matcha skin. One side is the headphone output ports, and the other side is the input cable.
